X9448WP24

The X9448WP24 is one member of the X9448 family which is designed as the monolithic CMOS IC that incorporates two operational amplifiers and two nonvolatile digitally controlled potentiometers. This device can be used to implement the amplifier as a wiper buffer in circuits that use the potentiometer as a voltage reference, and can also be combined with the amplifier yielding a digitally programmable gain
amplifier or programmable current source.

Features of the X9448WP24 are:(1)Two CMOS voltage operational amplifiers;(2)Two CMOS voltage operational amplifiers;(3)Can be combined or used separately;(4)Amplifiers:Low voltage operation, V+/V- = ±2.7V to ±5.5V, Rail-to-rail CMOS performance and 1 MHz gain bandwidth product;(5)Digitally controlled potentiometers: Dual 64 tap potentiometers, Rtotal = 10k, 2-wire serial interface and VCC = 2.7V to 5.5V.

The absolute maximum ratings of the X9448WP24 can be summarized as:(1)Temperature under bias: -65°C to +135°C;(2)Storage temperature: -65°C to +150°C;(3)Voltage on SDA, SCL or any address input with respect to Vss: -1 V to +7 V;(4)Voltage on any V+ (referenced to Vss): +7 V;(5)Voltage on any V- (referenced to Vss): -7 V;(6)VLead temperature (soldering, 10 seconds): 300°C.

The electrical characteristics of X9448WP24 can be summarized as:(1)Input current: 10 pA;(2)Input voltage range: V- to V+ V;(3)Response time: 200 ns;(4)Output current: -1 to 1 mA;(5)Power supply rejection ratio: 60 dB;(6)Input offset voltage drift: 6 V/°C;(7)Comparator enable time: 1 s;(8)Output low voltage: 0.4 V;(9)Output high voltage: VCC - 0.8 V.
